San Francisco’s Anchor Brewing announced the launch of Zymaster No. 4 today, Fort Ross Farmhouse Ale. Fort Ross Farmhouse Ale is a 7.2% Belgian-inspired Farmhouse Ale with a California twist with the addition of Yerba Santa. Yerba Santa, or “sacred herb”, as it is known by local Indians for its healing powers, provides a unique spiciness and bitterness that compliments the Farmhouse Ale flavors that we’ve all come to love.

Zymaster Series No. 4: Fort Ross Farmhouse Ale will be available in draught and 22-ounce bottles and will be poured in select bars and restaurants throughout the United States, as well as the Anchor Brewing Taproom in San Francisco, starting June 2013.
